DAQmx Create Timing Source (Digital Change Detection) (G Dataflow)

Version:
    Last Modified: February 6, 2017

    Creates a timing source that sends ticks to a Timed Loop on rising and/or falling edges of one or more digital lines.

    You can use this node only with devices that support digital change detection. For other devices, use the Digital Edge Using Counter timing source type. That node uses a counter and cannot detect edges on multiple lines.

    rising edge physical channels

    rising edge physical channels specifies the names of the digital lines or ports on which to detect rising edges. The DAQmx physical channel constant lists all lines and ports for devices installed in your system.

    You also can wire a string that contains a list or range of digital lines or ports to this input.

    falling edge physical channels

    falling edge physical channels specifies the names of the digital lines or ports on which to detect falling edges. The DAQmx physical channel constant lists all lines and ports for devices installed in your system.

    You also can wire a string that contains a list or range of digital lines or ports to this input.

    error in

    error in describes error conditions that occur before this node runs. This input provides standard 'error in' functionality.

    timing source name

    timing source name is the name to assign to the timing source this node creates.

    timing source out

    timing source out is the name of the timing source this node creates. Wire this output to the source input of the Input Node of a Timed Loop.

    If you specified a name for the timing source in the timing source name input, this output contains the same name. If you did not specify a name for the timing source, NI-DAQmx creates a name and sets this output to that name.

    error out

    error out contains error information. If error in indicates that an error occurred before this node ran, error out contains the same error information. Otherwise, error out describes the error status that this node produces.

    Where This Node Can Run:

    Desktop OS: Windows

    FPGA: LabVIEW NXG does not support FPGA devices
